and got practically nothing. lightdm org xfce4 doesn't seem to start at all. All I see is a terminal showing some last status messages like "lightdm ist starting". All I can do is to switch to another login terminal and change the config file to a bit depth of 30 and restart. That 10-Bit mode is working fine.gection "Screen"
Identifier "Screen0"
DefaultDepth 36
SubSection "Display"
Depth 36
EndSubSection
EndSection
What is causing this? Is this 12-bit mode simply not supported by the drivers - even not by the official one from nvidia? Do I have to change something in the xorg or kernel configuration and recompile? The graphics card I have should definitively support it. Could you please put some light into the dark?
